    Abstract: An all-solid battery includes a positive-electrode layer, a negative-electrode layer, and a solid electrolyte layer. The positive-electrode layer includes a positive-electrode current collector, a positive-electrode bonding layer containing at least a conductive agent comprising non-metal and formed on the positive-electrode current collector, and a positive-electrode mixture layer containing at least a positive-electrode active material and a solid electrolyte and formed on the positive-electrode bonding layer. The negative-electrode layer includes a negative-electrode current collector and a negative-electrode mixture layer containing at least a negative-electrode active material and the solid electrolyte. The solid electrolyte layer is disposed between the positive-electrode mixture layer and the negative-electrode mixture layer and contains the solid electrolyte. A concentration of a binder contained in the positive-electrode mixture layer is less than or equal to 100 ppm and a concentration of a solvent contained in the positive-electrode mixture layer is less than or equal to 50 ppm.

    Abstract: A positive electrode layer is to be used in an all-solid-state battery, and includes a positive electrode current collector; a positive electrode junction layer including at least a conductive agent and disposed on the positive electrode current collector; and a positive electrode material mixture layer disposed on the positive electrode junction layer and including at least a positive electrode active material including a plurality of particles, a solid electrolyte having ion conductivity, and a plurality of conductive fibers. The plurality of conductive fibers include a conductive fiber that is positioned to connect adjacent particles of the positive electrode active material. A concentration of a binder included in the positive electrode material mixture layer is 100 ppm or less, and a concentration of a solvent included in the positive electrode material mixture layer is 50 ppm or less.
